I hope those arent the same kinda pumps I tried the 1st time. On the one I bought the part that spins is connected by a tiny square plastic shaft in the middle. This shaft stripped it self the second time I turned it on and the part that is supposed to spin nolonger did. I was really bummed about it, which is why I went with my second choice of the aqualifter pump which has worked like a champ since.

Gotta Love it:

I called them on Wed 5/30 to check the shipping. They said it shipped the day before--Tues 5/29.

I just checked the UPS Tracking number--it shipped Thurs 5/31 !!! The day After I called.

I guess APT is just one of those companies.

Lol told you so! One month...

I guess I was lucky, both my pumps look identical, like the one to the right in your picture. One of them is silent, the other one noisy... I blame the different speed, requiring different "transmissions".

If you are getting sediments in your bottles, could that be a sign that you are mixing the solutions to concentrated?

That is a possibility, however I think if that were the case most of the sediment would be there from the beginning when I mix the solution, because it wouldn't disolve. It also could be because I am using tap water instead of distilled water to make my solutions. Either way it is such a small amount that I don't really worry about it.

If I put 12tsp of dry powder in 1 gal of water and by the time the reservior needs refilled there is say 1/16tsp of sediment at the bottom of the reservoir that is no big loss because 99.5% was still dosed to the tank.

I've also wondered if there was a maximum recomended concentration?

So far, I have my "airline" hanging an inch or so above the water line, through a plastic cable tie around one of the Eheim intakes. It seems so moist around there, I haven't seen any sign of clogging up yet... but I have only had it operational a few months and I'm still experimenting with dosing.

I also keep my dosing tube a couple inches above the max water level in my sump tank to prevent possible back syphon when the dosing pump is off. Mine has been running for about 8 months with no problems and no sign of residue build up on the tubing. I do get a tiny bit of sediment and staining in my fertilizer reservoir bottles, but not much and I just rinse them out every few months to prevent the sediment from building up to the point where it might get sucked up by the dosing pump.
